High Humidity reduces mechanical damage such as brittle paint but raises the risks of biological organisms, e.g. white efflorescence and green-to-black stains on a panel painting. [12] High Humidity also raises the risks of curving or warping of the wood over time, forcing the paint to flake off.
The ground of the painting was then removed by solvents or scraping, until nothing remained but a thin skin of colour, pasted over with paper and held together by the muslin. A prepared canvas was then attached to the back of the paint layer, using the same method as was used for lining pictures. When the glue had dried, the paper and muslin ...
Mummy portrait of a girl, AD 120–150, Roman Egypt, wax encaustic painting on sycamore wood. Encaustic is a method of painting that involves dry pigments mixed with hot beeswax, then applied to the surface of a support such as wood or canvas. A completed painting is then finished by taking a source of heat to reheat the surface and fuse it ...
The new lining canvas was pressed down onto the back of the picture by hand; then the outer edges of the lining cloth were fastened to the table by means of a large number of tacks, and a piece of wood with a rounded edge was passed over the back of the cloth, to ensure perfect adhesion.
Overpainting is the final layers of paint, over some type of underpainting, in a system of working in layers. It can also refer to later paint added by restorers, or an artist or dealer wishing to "improve" or update an old image—a very common practice in the past.

EBay was also accused of allowing the sale of at least 23,000 unregistered, misbranded or restricted-use pesticides, violating a 2020 "stop sale" order from the U.S. Environmental Protection Agency.
A completely unrelated type of "encaustic painting", not involving wax at all, is found in British ceramics, after Josiah Wedgwood devised and patented the technique in 1769. This was a mixture of ceramic slip and overglaze "enamel" paints used to imitate ancient Greek vase painting , and given a light second firing.
Wood stain is a type of paint used to colour wood comprising colourants dissolved and/or suspended in a vehicle or solvent. Pigments and/or dyes are largely used as colourants in most stains. The initial application of any paint or varnish is absorbed into the substrate similarly to stains, but the binder from a stain resides mainly below the ...
